Hi Dave. Yes I understand that but that doesn’t answer my query. Which is what is the duration of a WHOLE note in a measure of 6/8.

A WHOLE NOTE IN 4/4 = 4 quarter note beats

A WHOLE NOTE IN 6/8 = 6 eighth note beats

But if you select WHOLE NOTE in TablEdit the single note turns red indicating a timing issue as it sees the single note as a value of 4 quarter note beats rather than 6 eighth note beats. The duration of the measure.

A whole note in 6/8 doesn’t equal 6 beats. Dave is right. A whole note is 8 beats in 6/8 time. If you wanted a single note to fill up all 6 beats of a 6/8 measure, it would be a dotted half note. A dotted half note is made up of 6 eighth notes, and each eighth note gets a beat.
